You could cast your object to IEnumerable(T), then call ToList on it (.NET 3.5 required).

If you have .net 3.5 and System.Linq:

List<NewType> converted =
    myUnknownEnumeration.OfType<NewType>().ToList();

You need OfType to do the conversion (you can use Cast<>() instead if you want to throw an exception for any of the the wrong type) and ToList converts anything enumerable into a list.
